Aerosol Cartridge Sidewall Light Source for E-Liquid Visibility
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In low environment lighting conditions, users of aerosol-generating systems struggle to clearly view the remaining e-liquid level in the cartridge, making it difficult to determine when the cartridge needs to be refilled or replaced.
Innovation Solution
A cartridge design for aerosol-generating systems that incorporates a transparent region on the sidewall and a light source fixed to the sidewall, configured to transmit light into the liquid containing volume, enhancing visibility of the e-liquid level.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If a transparent housing is used to allow viewing of e-liquid level, then visibility of e-liquid level is improved, but illumination intensity in low environment lighting conditions deteriorates
Solution Approach 1:
A light source is introduced as an intermediary element between the external environment and the e-liquid level. This light source emits illumination that passes through the transparent housing, enabling clear viewing of the e-liquid level even in low ambient lighting conditions. The light source acts as a mediator that overcomes the insufficient ambient illumination without compromising the transparency of the housing.
2Illumination intensity
If a light source is added to illuminate the e-liquid level, then illumination intensity is improved, but device complexity increases
Solution Approach 1:
The light source is integrated into the cartridge structure and serves multiple functions: it illuminates the e-liquid level for viewing, and can potentially indicate liquid level status or provide feedback to the user. By making the cartridge multi-functional, the added complexity is justified by the enhanced utility and user experience, while avoiding the need for separate external illumination devices.
3Use of energy by moving object
If light source is positioned on inner surface of sidewall, then illumination efficiency is improved, but manufacturing precision requirements increase
Solution Approach 1:
Instead of requiring the light source to be positioned at a specific location on the inner surface, the design allows flexibility in positioning while maintaining functional effectiveness. The light source can be placed at different locations on the inner sidewall surface, and the system remains functional because the transparent housing and light path geometry accommodate various positions. This local quality approach reduces manufacturing precision requirements while maintaining illumination efficiency.

AI summary
A cartridge for use with an aerosol-generating system has a housing defining a liquid containing volume. The housing includes a sidewall extending from a mouthpiece end to a power supply end. The housing includes a transparent region forming at least a portion of the sidewall. The housing includes a light source fixed to the sidewall. The light source is configured to transmit light into the liquid containing volume. The light source may be fixed to an inner surface of the sidewall, fixed to an outer surface of the sidewall, or form a portion or the sidewall.
